Thanks Ken, you're a star! (& thanks for replying even though you don't sell my PCUT!)
Yep, i've got a CR630 PCUT bought in the UK and it seems that they are pure USB driven. The manual's rubbish though and if i'd known from the start i reckon i could've had it running within an hour!!
Anyway, all working now.... maybe the post and link will help someone else in my predicament!
